✦ Synopsis

Electrical resistivity of (MeBr-DCNQI)2CuI_xLi x shows that the metal-insulator transition of (MeBr-DCNQI)2Cu at 155 K is rapidly suppressed with increasing x. The mixed-cation system with x=0.2-0.5 retains a metallic state down to 4 K. The metal instability of DCNQI-Cu is discussed in the light of the mixed-valency of Cu.

The characteristic features of the metal-insulator transttion of quasi-one-dimensional conductors, (DCNQI)zCu, have been explained as being due to the unique cooperative onset of the Peierls transition and the Mott transition. It is also proposed that the reentrant metallic state results from the cr

We investigate the metal insulator transition of quasi-one dimensional organic conductors (DCNQI)2Cu by slave boson method. Within mean field approximation, we find that three interactions are needed for these organic conductors getting into insulator phase. These are an on-site Coulomb repulsion on
